We live in a very nice neighbourhood in the suburbs of Toronto (It is about a 40 minute drive into the heart of downtown).
The space for exchange is the main level and the 2nd floor of a house with a large garden.
Large kitchen, music room, new addition with large windows and ample parking in the driveway.

We are 7 kilometres from Lake Ontario, which has a bicycle trail. You can cycle many days east and west along the lakeshore.

Autumn is a beautiful time in Ontario, with the trees turning amazing hues of red and orange. There are plenty of opportunities in our area for hiking and mountain biking, as well.
Toronto is not only accessible by car, but also by a train running each 1/2 hour along the lakeshore.

On the lower level of our home (walkout basement) we run an AirBnb, which has been a joy. During a home exchange that area would either be vacant, or would be rented out to a professional person or couple. During a non-simultaneous home exchange, our guests would reside in our Airbnb.

We have 4 well-tuned bicycles in our garage, which can be borrowed. They fit adults from 5'4" to 6'2" tall.
